Professional Roof Cleaning in Northern NJ
Soft-Wash Only. Granules Stay On. Warranty Stays Valid.
Those black streaks aren’t dirt — they’re algae feeding on your shingles, and they spread. Most crews pressure-wash, blast off the granules, and quietly void your warranty. We soft-wash — the only safe method — to kill the growth and add years to the roof you already paid for. Our name on it, in writing.
Pressure washing destroys a roof and voids the warranty — and most companies do it anyway because it’s fast. We soft-wash, the only safe method, to stop the algae before it shortens your roof’s life. Call (973) 713-1053 for a free roof-cleaning inspection.
The Wrong Cleaning Costs You the Roof You’re Trying to Save
Here’s the part most homeowners don’t realize until it’s too late: those black streaks are actively shortening the life of a roof you paid good money for. That discoloration is Gloeocapsa magma — algae that eats the limestone filler in your shingles and strips the granules that keep them watertight. Moss is worse, holding moisture against the surface and prying shingle edges up until water gets under. Every month you wait, you’re trading away roof life you already paid for — and the wrong cleaning method speeds it up.
A proper soft-wash stops the damage cold and buys back years of shingle life — for a fraction of what replacing them early costs. We clean it the way that protects the roof and keeps the warranty intact, not the way that blasts it clean and quietly takes years off it. That’s the whole difference, and most companies get it wrong.
- Extends roof lifespan by removing damaging growth
- Soft wash method — no high pressure on your shingles
- Kills algae, moss, and lichen at the root
- Keeps your manufacturer warranty intact — pressure washing voids it
How We Clean Roofs
We use the right method for the job. Pressure washing destroys shingles and voids warranties — we never do it. Here’s what actually works without costing you the roof.
Soft Wash Treatment
Low-pressure application of a biodegradable solution that kills algae, moss, and lichen without touching a single granule. It’s the method shingle manufacturers including Owens Corning and GAF actually recommend — the one that keeps your warranty valid. Results are visible within hours.
Moss Removal
Heavy moss gets manually removed first — carefully, without lifting shingles. Then we treat the area with a solution that kills the root system and prevents regrowth. We also install zinc strips along the ridge if needed for long-term prevention.
Preventive Treatment
Already cleaned? We offer preventive treatments that keep algae and moss from coming back. Applied annually or bi-annually depending on how much shade and debris your roof collects. Much cheaper than a full cleaning every few years.
Most Companies Pressure Wash. That’s How They Wreck Your Roof.
Most companies will pressure wash your roof because it’s fast and looks dramatic. Here’s the problem: high-pressure water blasts the protective granules right off your shingles. Those granules are what shield the asphalt from UV and keep your roof watertight — once they’re gone, they’re gone.
After a pressure wash, your roof looks clean for a few months, but you’ve just knocked years off its life — and likely voided the warranty. Shingle manufacturers, including Owens Corning, whose products we install as a Preferred Contractor, specifically warn against it. We won’t be the company that hands you a clean roof and a dead warranty.
Our soft-wash method uses low pressure and a solution that does the work chemically, not mechanically. It kills the growth without touching the granules and keeps your warranty intact. That’s the difference between saving your roof and quietly destroying it — and it’s the only way we do it.
Our Roof Cleaning Process
Safe, thorough, and done in a single visit for most homes.
Inspection
We check your roof’s condition, identify the type of growth (algae, moss, lichen), and note any areas that need special attention or repair before cleaning.
Prep & Protect
We cover landscaping, wet down plants, and protect anything below the roofline. Our cleaning solution is biodegradable, but we take precautions anyway.
Soft Wash
Low-pressure application of our cleaning solution across the entire roof surface. The solution breaks down algae, moss, and lichen at the cellular level.
Rinse & Review
Gentle rinse, final inspection, and cleanup. Most roofs show dramatic improvement immediately, with full results visible within a few days as remaining growth dies off.
The Wrong Cleaning Method Costs You the Whole Roof
The dark streaks on your roof are algae — a living organism feeding on your shingles. Left alone it spreads and shortens the roof’s life. Cleaned wrong, it’s worse — pressure washing strips the granules and voids the warranty. The method matters more than the cleaning.
Algae and moss don’t just look bad — they actively break down the granules that keep your shingles watertight.
Most crews blast shingles, strip the granules, and void warranties. We soft-wash — the only safe method.
Clean it the right way before it spreads and you add years to your roof for a fraction of a replacement.

Got a question we didn’t cover? Call us.
Not the way we do it. Our soft-wash method uses low pressure — similar to a garden hose — and a solution that does the work. We never high-pressure wash asphalt shingles, because that’s exactly what strips granules, voids warranties, and damages the roof. The method is the whole point.
It depends on how fast growth returns on your roof. Some homes need cleaning every 2-3 years; others go 4-5. We set you up with a preventive treatment plan that extends the time between full cleanings — and we use the safe method every time, so each cleaning protects the roof instead of wearing it down.
We use biodegradable solutions and take extra steps to protect your landscaping — wetting plants before and after, covering sensitive areas. In our experience, plants do fine. We’ve never had a landscaping complaint.
Yes. Different materials get different treatment methods. Metal roofs can handle slightly more pressure. Tile roofs need very careful handling to avoid cracking. We adjust our approach based on your roof material.
We protect your landscaping first, soft-wash the full roof with low pressure and a biodegradable solution, rinse gently, and clean up like we were never there. You see before-and-after photos the same day. One company does the whole job — and never touches a pressure washer to your shingles.
Soft-washing won’t — in fact, manufacturers recommend it. Pressure washing can void your warranty, which is exactly why we never do it. As an Owens Corning Preferred Contractor, we follow their maintenance guidelines to the letter so your coverage stays intact.
